Title: Cylindrical magnetron shield structure
Inventor: SIECK PETER A
IPC: C23C14/35
Filed: 1994-01-07
Abstract: A rotating cylindrical sputtering target surface (29) as part of a magnetron has cylindrical shields (70) adjacent each end of the target (29) that are shaped at their respective inner edges (70) to maximize etching and to prevent condensation and subsequent arcing that undesirably occurs when certain materials, particularly dielectrics, are being sputtered. If two or more rotating targets (29) are employed in a single magnetron system, each is similarly shielded. In an alternative form, the target (29) is provided with a single cylindrical shield (69) that is cut away for a significant portion of the distance around the cylinder to provide an opening through which a sputtering region of the target is accessible, while maintaining shielding of the target end regions. This alternative single shield (69) is similarly shaped at portions of its inner edges adjacent to the opening to maximize etching and to prevent undesired condensation and subsequent arcing. The preferred shield structure (69) is rotatable in order to allow the position of the sputtering activity to be selected.

Title: Method and apparatus for reproducing/recording at variable speeds dependent upon the bit rate of the mpeg encoded signal
Inventor: YANAGIHARA NAOFUMI
IPC: H04N21/432
Filed: 1995-11-14
Abstract: When a transport packet of the MPEG2 signal is recorded, a tape speed is reduced to 1/2 or 1/4 of that used to record standard data in accordance with the bit rate of the program. Twa heads (A and B) having different azimuths are provided in close proximity with each other at the same height on a drum. If the 1/2 tape speed mode is selected, the recording is performed by head A during the first scan of the tape and by head B during the next scan. Even when the tape speed is a fraction of an even number of the standard tape speed, the azimuth angles of adjacent tracks are different and azimuth recording is performed to reduce crosstalk.

Patent CA-2182990-A1 (CA)
Inventor: ARCI FRANCESCO DAVIDE LUIGI
IPC: G06N3/00
Filed: 1996-08-08
Abstract: A computer system comprises at least one genetic optimization agent holding a pool of genotypes, representing possible solutions to a problem. The genetic optimization agent generates new genotypes from the pool, evaluates the new genotypes according to predetermined fitness criteria, and selects the fittest of the genotypes to form a new generation of genotypes in the pool. The system also includes a number of further agents, for generating further solutions to the problem, using different techniques, such as simulated annealing, constraint logic, and neural networks. These further solutions are also represented by genotypes. The genetic optimization agent imports genotypes from the further agents and adds them to its pool of genotypes for breeding and selection. The genetic optimization agent thus provides a way of integrating a number of different problem-solving agents, in such a way as to achieve synergy between them.

Title: Process and apparatus for the gas-phase polymerization of alpha-olefins
Inventor: GOVONI GABRIELE
IPC: B01J19/24
Filed: 1996-07-17
Abstract: Process for gas-phase polymerization carried out in two interconnected polymerization zones, to which one or more .alpha.--olefins CH2=CHR are fed in the presence of catalyst under reaction conditions and from which the polymer product is discharged. The process is characterized in that the growing polymer flows through a first polymerization zone under fast fluidization conditions, leaves said first zone and enters a second polymerization zone through which it flows in a densified form under the action of gravity, leaves said second zone and is reintroduced into the first polymerization zone, thus establishing a circulation of polymer around the two polymerization zones. The novel process allows olefins to be polymerized in the gas phase with high productivity per unit volume of the reactor without incurring the problems of the fluidized-bed technologies of the known state of the art.

Title: Method of increasing corrosion resistance of metals and alloys by treatment with rare earth elements
Inventor: LU YUCHENG
IPC: C23C22/68
Filed: 1995-10-10
Abstract: There is provided a method for treating the surface of metals such as ferritic steels, austenitic stainless steels, copper and aluminum alloys to increase their corrosion resistance. The metals are immersed into a heated aqueous composition containing a rare earth salt. Increased corrosion resistance is obtained using nitrates of yttrium, gadolinium, cerium, europium, terbium, samarium, neodymium, praseodymium, lanthanum, holmium, ytterbium, dysprosium, and erbium nitrates. The rare earth salt is present in the range from about 2%  by weight to saturation of the solution. The composition includes a pH-modifying substance such as nitric acid to adjust the pH in the range 0.5 to about 6.5 to attack the surface to remove oxides facilitating deposition of the rare earth. For aluminum alloys the pH is maintained between 4.5 to 6.5, for nickel based alloys and austenitic stainless steels the pH is maintained between 0.5 to 3.5 and between pH 2.0 to 4.5 for ferritic stainless steels.  The surface can also be conditioned by abrasion before or during immersion in the composition. Increased corrosion resistance is achieved by immersion for 15 to 20 minutes with the composition maintained between 60 to 95 ·C.  Gadolinium, neodymium and praseodymium nitrate when used alone produced the greatest degree of corrosion resistance compared to the other rare earth nitrates. Significant synergistic effects are observed when combinations of two or more rare earth nitrates are used in the compositions. Compositions based on cerium nitrate, gadolinium nitrate and lanthanum nitrate are very effective in reducing crevice corrosion.

Title: Improved accuracy in cell mitosis analysis
Inventor: KAMENTSKY LEE D
IPC: C12Q1/68
Filed: 1995-10-05
Abstract: Cells, stained with a fluorescent dye taken up by DNA in individual cells, are scanned with a cytometer. The integrated values of all the cells are compiled to create a histogram of cell counts versus integrated fluorescent light (fig.  2), representing populations of cells having a complement of DNA, but not in the process of division (G0 phase), cells having two full complements of DNA, but which have not actually divided into two cells (G2 phase) and cells in the process of replicating their DNA (S phase). Errors, resulting from statistical errors, focusing problems, inaccurate measurement of background, etc., in the integrated values and the histogram, and affecting the accuracy and prognostic value of the peaks and separation phases, are corrected by modeling the convolution of the error function with the signal function, and removing the error function, by deconvolution, from the G0 and G2 peaks and the S phase (fig. 14).
